To a, whom t may concern.'

Be it known. that I, .I AMES H. COOK, .I r., a citizen of theUnitcdStates, residing at Homer, in the county of Calhoun and State ofMichigan, have invented certain new and useful Improvements in Knives,of which the following is a specification, reference therein to theaccompanying drawings.

The invention consists in the peculiar construction of a pocket knife,comprising a casing in which a'blade slidingly engages, a pin secured tothe blade extending through a slot in the casing'and connected to aplate on the outside, which when turned atan angle to the casing may beemployed as a handle to slip the blade in or out, and when turnedparallel therewith forms a complementary portion to the handle wh en theblade is opened or closed.

The construction is designed to make what I call a safety pocket knife,that is one which cannot be closed on the hand when using it, also whichis free from dirt by having the casing entirely inclosed when the bladeis withdrawn and dispensing entirely with the use of springs.

The invention further consists in the peculiar construction, arrangementand combination of the various parts as more fully hereinafterdescribed.

In the drawings, Figure 1 is a perspective view of my improved knife,showing the blade withdrawn and the cover or actuating plate turnedslightly from its closed position.. Fig. 2 is a plan view showing theblade partly extended. Fig. 3 is a vertical, central, longitudinalsection therethrough, when the blade is entirely extended.v Fig. 4 is across section on line :l: @c of Fig. 2.` Fig. 5 is a horizontal sectionthrough the connecting pin, showing the casein plan.

A is a casing closed on all sides, having the opening B at one end. 'Cis a knife blade therein, of a length to be inclosed entirely within thecasing.

D is a pin pivotally secured at the base or butt of the knife blade andhaving the flat portion E engaging through a longitudinal slot F in oneof the side walls of the casing being had through the reverse operation,

A. At each end this slotis provided with an enlargement G which may havestops or 5o shoulders II on opposite sides, against which the vsides ofthe dat portion E off the pin is adapted to'engage when turned atrightangies to the slot. f 1 I is aplate secured near one end to theouter end of the dat yportion E of the pin and forming a handle, bymeans of which the blade may be extended from the casing or withdrawntherein.

J is a hook at one end of this plate adapted to form a cover for theopen end B of the casin'g when the blade is withdrawn. A

The parts being thus constructed their op eration is as follows: In theclosed position of the knifethe hook .I engages over the open end B ofthe casing and thus closes the only point through which dirt might findaccess to the interior, the plate proper covering the slot F. To openit, the operator turns the plate at right angles to the casing, in whichposition the iiat portion E of the pin registers with the longitudinalslot F. Then using the plate as a handle, the knife blade may be slidout of the casing, as shown in Fig. 3 The plate may then be turnedparallel with the casing, the hook portion engaging over the butt oflthe casing, as shown in Fig 3, and forming a complementary portion ofthe handle. In this position the sides of the dat por- ,tion' E of thepin engage against the shoulder I-I at the forward end of the slot,which securely locks the blade against being withdrawn.

To withdraw the blade the operator goes that is, turns the plate to aposition at right angles to the casing, sliding the pin through the slotto the butt and then turning the plate upon the pivot, engaging the hookover the open end of the casing. In this position the pin engagesagainst the shoulders H, of the enlargement G at the butt of the casing,which prevents the withdrawal of the blade until the plate is againturned at right angles to the casing. Thus I obtain a knife in which theblade is locked in its closed position, locked in its open position andprovided with a casing which is dust proof, obviating all use of springsand the trouble connected therewith. Any desired shape of blade may beused and the pin and plate may be varied also to cover any means oflocking the pin by turning it in opening and closing.

NVhat I claim as my invention isl. In a knife, the combination of ahollow case, a blade sliding therein, a pin extending from the base ofthe blade and entering a longitudinal slot in one side of the case, anda plate secured to the outer end of the pin, adapted to be turned at anangle to the case, adapted to form a handle to move the blade, and toform a complementary portion thereof when the blade is open or closed,substantially as described.

2. In a knife, the combination of a hollow casing, a blade slidingtherein, a `pin extendase of the blade through a lonf n the side ofthecasing, apl'ate` e outer end of ,the pin, i turned at an angle orparallel le, and means for locking the ou ad de 2O z5 with the handblade in its open and cl movement of scribed.

3. In a knife, the com casing, open at one en when the plate is ovtially as described.
